Revert of Enable spec-compliant algorithm for MediaStream video constraints by default

Revert of Enable spec-compliant algorithm for MediaStream video constraints by default (patchset #2 id:40001 of https://codereview.chromium.org/2793053002/ )

Reason for revert:
Regressed performance_browser_tests 21-93% (see crbug.com/710187). Suspect that chrome.tabCapture extension API is providing constraints in the legacy format, and this feature switch is causing bad defaults to be used instead.

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2816533003/ by guidou@chromium.org.

The reason for reverting is: The defaults were changed to the same as the old
algorithm in subsequent patches..

I created the reland, but will actually land it only after confirming that the
new patches restore performance.
